We present two geometric proofs for KochenSpecker’s theorem [S. Kochen, E. P. Specker: The problem of hidden variables in quantum mechanics, J. Math. Mech. 17 (1967), 5987]. A quite similar argument has been used by Cooke, Keane, Moran [R. Cooke, M. Keane, W. Moran: An elementary proof of Gleason’s theorem, Math. Proc. Camb. Phil. Soc. 98 (1985), 117128], and by Kalmbach in her book to derive G...

This study investigates the dynamics of limited homogeneous populations based on Moran-Ricker model with time delay. The delay in density dependence caused preceding generation to consume fewer resources, leading a decrease required resources. Multimodality is evident model. Some insect species can be described by Moran–Ricker Bifurcations associated flipping, doubling, and Neimark–Sacker for c...

Although heightened throughout childhood and adolescence, sweet taste preference declines during late adolescence (Desor et al., 1977; Desor and Beauchamp, 1987). Despite such age-related changes in sweet preferences, individual variation, due to both genetics (Bartoshuk, 2000) and experience (Beauchamp and Moran, 1982, 1984), exists at both ends of the age spectrum (Desor et al., 1977; Beaucha...

* This paper was inspired by a conversation Berman had with his great uncle Rafuel Grinspun, shortly after the latter migrated from the Soviet Union. We appreciate the helpful comments of Lawrence Katz, Kevin Lang, Shlomo Yitzhaki and seminar participants at Boston University, the Hebrew University, Maryland, Yale, Michigan, MIT and an NBER Labor Studies session. We thank the Maurice Falk Insti...

Several groups have recently modeled evolutionary transitions from an ancestral allele to a beneficial allele separated by one or more intervening mutants. The beneficial allele can become fixed if a succession of intermediate mutants are fixed or alternatively if successive mutants arise while the previous intermediate mutant is still segregating. This latter process has been termed stochastic...

one of temperature estates is hot day occurrence. in order to recognize the mechanism of this estate, surveying its spatial behavior is crucially important. in current paper it has been attempted to recognized widespread hot days and their spatial distribution by using statistical methods. accordingly maximum temperature database of iran during 1962-2008 has been used. the analyses result has i...

MOTIVATION A fundamental problem in population genetics, which being also of importance to forensic science, is to compute the match probability (MP) that two individuals randomly chosen from a population have identical alleles at a collection of loci. At present, 11-13 unlinked autosomal microsatellite loci are typed for forensic use. In a finite population, the genealogical relationships of i...

Endemic Burkitt's lymphoma (eBL), the most common childhood cancer in sub-Saharan Africa, occurs at a high incidence in western Kenya, a region that also experiences holoendemic malaria. Holoendemic malaria has been identified as a co-factor in the etiology of this cancer. We hypothesized that eBL may cluster spatially within this region. Medical records for all eBL cases diagnosed from 1999 th...
